Be it known'that I, EUGENE D. Jurrie soN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented cert-ain nevv and useful l Improvements in Vomiting- Keirs; and l do hereby declare the followskilled in the art to which it appertainsto make and use the same.'

This invention relates to an improvement in vomiting keirs. The object of -theinvention 4is toreorganize and improve the-construction of vomiting keirs. Certain features of the invention relate to improvementsV of .construction ofthe vomiting keir illustrated and described in the patent granted to ine" November' 22, 1904, No. 77'5.-h Y i l ln mills or bleacheries Where these keirs are used,-tl1ey are ordinarily arranged in batteries'wv'itn a 'floor nearfthe topfof 'the cylindrical portion of fthe keirs for convenience in 4bringing :materials to and taking them from them; Each keirfjhad separate automatic mechanism for-opening and clos` ing the motive steam valve, which,` because of its functional relation to the keir,- Was necessarily7 locatednear the bottom'rof the kein Onesimpliiication which the present Vits parts invention contemplates is providing asingle mechanism Vfor operatingithe valves of air entire battery of keirs. Thus the controlszfor the battery of keirs' are banked together in a single-unit, which may be con- 4yeniently located above the vfloor line vand therefore easy of access. One featureof'the Yinventionl resides inl this Vbanking'of `the keir controls.`l Y

It will be noted that in the keir of the said patent, the'automatic'means for Iopening and closing-the'motivc steam valve is locatedin the bottom of the pit nearithe keir. All of are','therefore, exposed to theI action of the liquor, which necessarily subjects them to severe working and Wearing conditions. According-'to the present invention, the greater portion ofthe operativeparts of the. keir.' such as valves and mechanism, are raised 'above the liquor line. so as to improve the wearingconditions and prolong 'thelife of the/'parts'. Not only doesthis Aincrease the'idurabilityf of thev apparatus, but it iiicreases yeeonomy off4 operationbby reducing Specification of Letters Patent. i

.the time keir.

In the keir of the said Apatent'the Vautomatic means vfor 'opening and closing `the motive steam valve is actuated to be'opened and'closed as a result of a rise or fall of the level of the liquor in'the trap,

necessarily required to operate the and therefore Patented sept. io, isis.

the vomitingactiongis dependent uponvthe rate of flow ory seepage of the liquor through the materials, so thata substantially 'uniform amount of liquor i's vomited into the top of the keir 'at intervals idependentupon its rate of collection. present invention, the vomiting actionjtakes placer at uniform intervals of time, i-rrespecl tive.' of the amountof liquor which has seeped or'lovved into the trap. While VeX- cellent lresults were obtained-*bythe use of the mechanism of the said patent,- it has been found that superior results' are obtained* by making the vomiting action posi-- tive and dependent upon -a 'timed interval rather thanupon theflovv of liquor through the materials One'reason for this is belicved tobe dueto the fact thatthe How of liquor'into thetop of the keir is more frequent and gentle, instead `of being more' iufrequent, sudden and more or less violent. Incidentally, the present invention subjects the operating parts, suchfas valves and other f to considerably less Wear, and l elements, 4 avoids hammer and incident deterioration.

One of` the important advantages ofthe present construction resides inthe diminished steam consumption, conducing to its economy of operation. In addition to the foregoing features and `advantages of the present construction, it is to be observed that the mechanism is simpler, and this also commends it to users. y -ln the accompanying drawings, Figure l is a sectionalelevation illustrating a single keir, and a single controlling means; Figs. Q and 3 illustrate, respectively, a `front and sectional lend elevation of a banked control for a battery of S keirs; Fig'. Lis a detail hereafter referred to; and Fig. 5 isa diagrammatic illustration of a battery of keirs provided with a banked control.

The illustrated embodiment of the, invention is described as follows z-,The keir Vproper l consistsI of the usual sheet metal According Vto the.V

on which the materials to be treated are laid. yEhe vomiting pipe consists of a pipe and suitable connections forming a closed passage connecting the top and bottom et' the izeir. This vomiting pipe is indicated in a general way by the reiference character d, which is intended to designate the pipe as a whole. Ii portion oi' the vomiting pipe, extending troni the hettom ot the heir? leads through the check valve (i, which prevents haelt-(low et liquor into the bottoni ot the heir. rthe pipe 5 discharges into the bott-om o'l a tra-p T which is made considerablylarger than the vomiting pipe proper and su'lticient to hold a considerable hody o't liquor. luto the trap T depends a pipe 9 which extends up through the top ot the trap T and to the checleelbow A pipe l0 leadsl .trom the elbow 9 to the 'l' ll which discharges into the lreir in the usual manner. The liquors percolating through the materials in the heir lind their way through the pipe 5 and cheel; valve (5 into the trap T where they collect and remain until discharged into the top ot the heir. The liquor is forced up through the vomitingl pipe by means et steam pressure, a motive steam pipe l2 being provided, which discharges live steam into the top ot the trap T at regular intervals ot time. The steam supply pipe if?, leads steam through the T lit to the hand valve l5. and thence to the automaticallf.v controlled valve 1G, from which it flows through the elbow 1T to the pipe l2 in which located a second hand valve 1S. From the T lai a branch pipe 19 leads through the valve 2O to the vomitingpipe 'l0 and affords means tor admitting steam to the heir tor the purpose of heating it. vent pipe '2l leads from the top ot the trap 7 to the check elbow 9, and aiiiords limited free communication between the top and bottom ot the lteir at all times`r so as to equalize the pressures and allow the liquor ireely to tlow into the trap 7. The vent pipe 2l is small. aad does not niaterially reduce the i'nessure frted by the steam upoiI the liquor in the trap. hut it is suiheiently large to permit the steam to escape Vfrom the trap a'liter the motive steam valve has .been closed; it is provided with a rhecl valve (mening toward the top et the lveir at. its upper end. Ythe mltonritii'allv controlled valve lil if; operated h v means olf an electric motor 122, which. through reducing gearing. opens and closes the valv:l l S trom time lo time during the progress of he boiler operation, The motive steam valve is shown in Figs. 5l and l. and will he iileserihed in connection with the tl f,sci.'i1,)tion of the lrfinlved control illustrated in those figures. lt is sutlirient here to note that the motor 22 is supported upon a i'iedestal conveniently mounted on the elbow l?. The steam gage El indicates the pressure ot the motive steam, and the steam gage Q5 indicates the pressure in the lteir.

The tloor itl located near the top of the cylindrical portion ot' the heir, and all ot the hand valves and automatic mechanism for operating the heir are located above this floor leveldin tact, the only valve below the floor is the check valve t) which necessarily is required to remain in position at the bottom ot the lreir.

rThe operation ot the. apparatus is snhstaib tially the same as the operation of the apparatus of said patient. except that the opening and closing ot the motive steam pipe is per formed at timed intervals instead oit at intervals dependent upon the rise and tall oi' the liquor level in the trap. Brieily. the operation is described as tollowsellvhen the liquor in the heir flows outy into the vom iting pipe, it gradually rises in the trap T until the motive ste: n1 valve 1G is opened, and then live steam is admitted through the pipe. 12 to the top ot the trap, and the pressure exerted h v the steam on the liquor in the trap closes the cheek valve (i and forces liquor out of the trap up through the vomiting pipe et and into the top of the ireir as longl as the motive steam valve remains open. lWhen the motive steam valve closes, the pressure 'tails in the trap. and the flow of liquor from the l-zeir into the trap is resumed.

The mechanism ot the banked control is described in connection with Figs. 2, 3, t and 5 as tollows2-The main steam supply pipe consists of ariser, which is connected at its lower end with the steam main or boiler and at its upper end with a multiple T having as many discharge pipes 5l as there are lreirs. Each discharge pipe 51 is controlled by a hand valve an automatically controlled valve 53, and a second hand valve 5a on the heir side of the valve The valves and 54 are the usual steam valves. The valve 53 is associated with each heir, and it is opened and closed at timed intervals to admit steam to the trap et the particular keir which it serves. In Fig. 3 a section of the valve is shown. The valve member is integral with the stem 6l which is normally held in raised posit-ion by the spring G2.. a cover 63 being provided tor insertion and removal ot the valve and stem. The valve stem 61. projects upwardly through the stutting bei; Git and is serewthreaded upon its upper end at. (l5. A nut titl.y provided with an upwardly extended stem (i7, is screwed on to the upper end of the valve stem (31 and held in place by a lock nut 68. A valve slide is provided with a socket, 7l which receives the stein (ST et the nut 6G. This valve slide 70 is depressed atregular intervals. and when depressed, it pushes down the valve stem and opens the motive steam valve llVhen it rises, the steam valve is closed by its spring. rEhe valve slide carries a timer gib 72, which consists of a right-angled 'adjusting it to the-right, the

'0n 5ft are shown inposition;v on theiright-'liand maaier This timer wheel v7G rota-tes in the direction of the arrow 77, and the pins 75 strike the y timer gib and depress the valve slide 70, thereby opening the valve. vWhen a pin 7 5 passes beyond the end of the timer gib 72, the valve closes. It will be notedthat by adjusting the timer gib to the left, as seen in Fig. `1,'the duration of the opening of the k'valve 53 will be shortened, and that by duration of the opening will be lengthened. It will also be noted that the amount of valve lift may be adjustedvby loosening the check nut 68 and turning the nut 66 up or down as desired.

VThe upper end ofthe valve slide 70 is forked, as shown in Figs. 3V and 4, and embraces the Vtime shaft 7 8 by which it is steadied. Pivotally mounted on the valve slide isa latch provided with aV ball handle 81 bywhich Vit is manipulated by the` operator.rv The right-hand end 82 ofthe latch, as vseen in Fig. il, is forked, and in thel position shown in F ig. 4:, it is inserted in the space between the lower end ofthe valve slide and-the upper-surface of the nut 66. With the latch in this position, the timer gib on the valve slide is lifted high 'enough to be engaged by lthe pins 75; and when the forked endv 82 of the latch is. withdrawn ,fromy between the lower end of the valve slide 70 and the upper4V surface of the nut'66, the yslideis .permitted to fall a distance equal to thethickness of thefork 82 of the latch, so as thereb y to lower the valvey slide a distance suiicient to bring the' timer gib below-the path of motion of the'pins 75. By this construction the motive steam valve may be thrown cut ofoperation, although thetimer 4wheel continues to run. All of theftim'er wheels 7 Gare mounted side by sidevon the tiineshaft '78, as shown in 4F ig. 2,` and any one ora-ll ofthe steam valves 53 may be `thrown out of operation or linto operation .ati pleasure,

without the left-hand side of Fig. 2 thetvalv'es side of this figure these valves 51 havcbeen omitted for clearness of illustration of'the valves 53.y f Y By reference to Fig. 3, it will beA seenthat the timer 'wheel 7 6 is provided with six holes to receive the pins 75. lVhen one pin only is inserted' inone of the holes,as 90 for example, there will be one opening of the valve 53 it each revolution ofthe timer wheel. 1When the holes 90 and 93are provided with pins 75, there will be two openings of the valve for each revolution of the timer wheel.` Then lioles-90,-92 and 941are 'the timer wheel, and Whn *other inotorf is used.

^ rially, and inse. Each valve 53 bea-rs a number, which 165 Acorrespon,de tothe number of a ker, and when it isdesir'edto throwanykeir into and out i operation,- th'e manipulation of the latch of tl'ieappiopriat'e valve throws the keir into y t iris claimedrsf interfering with any"otherva`lve.

This, affords a convenient means for timing 70v the opening of the motive steam valves.

The time shaft 78 is mounted in bearings 100 which are supported from a shelf 101, Acaliried by the bracket 102 mounted `on the wall or otherwise.r The time shaft 78 is provided with a worm wheel 103 which is 'driven by a worin 104 mounted 'on a shaft 105 supporte'dain bearings 106 carried by the shelf 101. Af worin wheel 107 is mounted upon the shaft 105 land driven by a worm 108 mounted on the worm shaft 109 which is adapted to be coupled by clutches tothe nio-f tor 110, or the motor 111. A lever 112 pivoted' at 113 is provided to shift the clutches so aste connect the wor-'m with either motor.

- The niotors are supported on the blocks 1141,

which are bolted tothe shelf 101. Suitable switches' for the motorsV have provisioi'i 'for `runi'ilingeither the one motor or the other,

as may be desired, so thatin case of breakdownof :one motor, the other motor Amay be used, or. one motor may be rested while the The n operating devices for each of the valves 53 are identical with the operating devices for the valve 16 in the single keir unit,'su'ch as is 'shownin Fig. 1.
